"Animal insulin is the Lindbergh of the space shuttle age," said Dr. John H. Holcombe, senior clinical research physician for diabetes care at Lilly. "It's antiquated."
Dr. Loren Grossman: In many but not all cases, people who switched from animal insulin to human insulin, when they were under very careful supervision, were able to make that switch and make those adjustments. But as I said, there are some people, for reasons I can't explain, because I don't know individual cases, who have not been able to do so. Maybe there are differences in their antibody responses. Maybe there are unpredictable, different antibodies we don't know about. Most people have been able to make the switch by adjusting the dosage. Some have not been able to.
Dr. Loren Grossman: I don't know. It's a small number. I don't know that. But we are continuing to produce pork insulin. This announcement of discontinuing only one formulation does not prevent people from continuing on the animal insulin they need.
